AB  - A novel analytical method was developed for the determination of organic acids 
      (formic acid, acetic acid and propionic acid) in 1, 2-butylene oxide (1, 2-BO) 
      products by valve switch-ion chromatography (IC).The samples were diluted in 
      ethanol, and then were eluted from a concentrator column (IonPac TAC-ULP1) to an 
      analytical column (IonPac AS11).The extracts were detected by a suppressed 
      conductivity detector.Formic acid, acetic acid and propionic acid were separated 
      well.Good linear relationships for the three organic acids were obtained.The 
      spiked recoveries of the three organic acids in the samples were in the range of 
      92.5%-111.8%.The relative standard deviations (RSDs) were less than 5.6%(n=3).The 
      limits of detection (LODs, S/N=3) of the formic acid, acetic acid and propionic 
      acid were 0.60-4.80 mug/L.The method is simple, rapid, and accurate, and is 
      suitable for the determination of the organic acids in an insoluble organic 
      system.
